Just as critics had predicted, ObamaCare has again proved itself a job-killer.

Especially for Democratic senators.

Even before the full results were in last night, it was clear ObamaCare had again retired more of those whose votes brought us ObamaCare.

That’s no surprise, given how most Democrats did everything they could to avoid even uttering the word “ObamaCare” during their campaigns.

ObamaCare wasn’t the only issue, of course.

Democrats are paying the price for a weak president who is openly mocked by our enemies abroad and whose leadership at home raises questions of partisanship and competence at some of our most important institutions, from the IRS and Justice Department to the Centers for Disease Control and our veterans hospitals.

Even so, no legislation has dominated an election the way ObamaCare did the Senate on Tuesday.

Partly, this is because it was the president’s signature issue, and most Democrats who went down to defeat had themselves at one time echoed the many falsehoods the president made on its behalf: Premiums would go down, it would become more popular over time, you could keep your doctor, the individual mandate wasn’t a tax, etc.

In this election, ObamaCare served as a convenient shorthand for arrogance and overreach. When it came down to it, the advocates of “Smart Government” couldn’t even produce a functioning Web page.

Much as the mainstream press has tried to diminish the role of ObamaCare in these midterm elections, the president had it right: It was his policies on the ballot. And they’ve now given the GOP the Senate.
